GEORGE W. DENIEF, OE LOWELL, MASSACHUSETTS.

SPECIFICATION forming part ofLetters Patent No. 786,960, dated April 11, 1905.

Application led December 6, 1903.' Serial No. 184,307.

To all whom. it may concern:

Be it known that I, GEORGE W.y DENIEF, a citizen of theUnited States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Valves, of which the following is a specification.

My invention relates to new and useful improvements in valves, and more particularly to faucets and similar devices. Its object is to provide a device of this character having removable working parts, the same being so constructed and arranged as to be readily7 replaced when worn.

The great difficulty experienced with faucets is the wearing of the valve-seat and the thread employed for operating the valve.

The object of invention is to overcome these objections by employing an internallythreaded detachable tube in which is mounted the rotary valve of the faucets, and secured to the end of this valve isa detachable washer for sealing the faucet and a detachable valveseat, which is secured in place by the tube.

With the above and other objects in view the invention consists in the novel construction of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which- Figure 1 is a section through a faucet constructed in accordance with my invention. Fig@ is a section on line 2 2,`Fig. 1. Fig. 3 is a detail view of the threaded tube. Fig. 4

` is a detail view of the detachable valve-seat.

Referring to the figures by numerals of reference, 1 is the body of the faucet, the same having a partition 2 therein, in rear of which is located a detachable valve-seat 3. This yvalve-seat has an aperture 4 therein in alinement with an extension 5 of the body, and the upper end of this extension is normally closed by a cap 6, which is externally screw-threaded and adapted to engage threads 7, formed upon the outer face of the extension 5. Suitable packing 8 may be interposed between the cap 6 and the end of the extension 5. Longitudinally-extending grooves 9 are formed within the extension 5 and are adapted to receive lugs. 10, arranged at opposite sides of an intube 11.

Y iternally-screw-threaded tube 11. This tube is adapted to be seated on the detachable valveseat 3 within the extension 5 and has a cutaway portion 12 at its lower end, which registers with the outlet 13, formed within the partitionQ. A screw 14 is mounted in the tube 11 and has a stem 15 projecting therefrom and through the center of the cap 6, said stem being provided with arm 16, whereby it may be readily rotated. Ametallic disk 17is arranged upon the lower end of the screw-14 and is spaced therefrom by a washer 18, of rubber or other suitable material. This disk and washer fit snugly within'the tube 11 and are held in place bya screw`19, which extends into the inner end of the' screw 14 and holds a washer 2O in place upon the disk 17. This washer 2() is of such size as to close the aperture L1, and the disk 17 serves to compress it upon the valve-seat 3 when the faucet is closed. When it is desired to open the faucet, the stem 15 is rotated so as to move the screw 14 upward within the The disk 17 will move upward and relieve the washer 2O from pressure, and said washer` will also be carried upward with the screw, and thereby open the aperture 4 and permit water to flow upward through said aperture and the outlet 13. When any of the parts become worn, they can be readily replaced by iirst removing the cap 6. The stem 15 is then drawn upward and will carry the tube 11 therewith, thereby disengaging the lug 10 `from the grooves 9. Should the threads within the tube become injured, a new tube can be readily substituted therefor, and should the washer 20er the valve-seat 3 be worn or destroyed new ones can readily be substituted by detaching the tube 11 and inserting a new washer 2O or a new valveseat 3.

While I have shown this form of valve used in connection with a faucet, it will be understood that I do not limit myself to such use,

for, if desired, the same can be employed in connection with any form of cut-0E.

It will be understood that the valve-seat can be formed of any desired material, preferably of brass in hot-water valves and glass in cold-water valves.

In the foregoing description I have shown IOO the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus fully described my invention, what is claimed as new isu In a device of the character described, the combination with a valve-casing having an outlet, and an extension; of a flat detachable metallic valve-seat within the casing, an internally-screw-threaded non-rotatable tube within the extension and bearing upon the valve-seat to hold the same rigidly in position, said tube having an'opening through one portion thereof which registers with the outlet in the valve-casing and the valve-seat being` wholly independent of and free from engagement with the tube, means for detachably se- GEORG E W. DEN IEE.
